Question

7m+4/m+2 = -4/3 please help me to solve the equation and get the value of m​

Answer 1

Answer:

Step-by-step explanation:

do it simple yar , lcm

     7m + $\frac{ 4 }{ m }$ + 2 =  $\frac{ -4 }{ 3 }$

     $\frac{ 7[tex]m^{2}$ + 4 }{ m }[/tex]  =  $\frac{ -4 }{ 3 }$  -  2

    $\frac{ 7[tex]m^{2}$ + 4 }{ m }[/tex]  =  $\frac{ -4 - 6 }{ 3 }$

   $\frac{ 7[tex]m^{2}$ + 4 }{ m }[/tex]  =  $\frac{ -10 }{ 3 }$

   7$m^{2}$ + 4     =   $\frac{ -10 }{ 3 } * m$

     7$m^{2}$  +   $\frac{ 10 }{ 3 } * m$  +  4    =  0

         multiplying by 3 both sides

    21$m^{2}$  +  10m  +  12    =  0

   by applying an Indian mathematician Sridharacharya formula

      $\frac{-b ± \sqrt{b^{2} - 4ac } }{2a}$

now we have to find  m

   m   =    $\frac{- 10 ± \sqrt{10^{2} - 4(21)(12) } }{2(21)}$

               $\frac{- 10 ± \sqrt{ 100 - 1008 } }{ 42 }$

            a symbol is enough for intelligent

so I hope you will carry out the further calculations

if you are unable , then I am available to solve it.

say me in comment if you want to solve this by me
